Group C: Invasive Species Interactions With Other Stressors Q1: Critical Scientific Issues Climate change Drought & extreme weather Increasing CO 2 Fire Multiple invasives and native pests Recreation Pollution Fragmentation Development and oil & gas extraction Transportation corridors Harvesting, thinning, restoration

Group C: Invasive Species Interactions With Other Stressors Q1: Scientific Issues Integrated frameworks Drivers vs passengers (MacDougal 2005) Who is the driver? Who is the passenger? Modelling changes in potential native and invasive species distributions (niches)

Group C: Invasive Species Interactions With Other Stressors Q2: Critical Management and Policy Issues Increase capacity to prioritize &conduct mgt activities Develop public trust. Improve public support Increase effectiveness of agency collaborations Increase relevancy to stakeholders, decision-makers and funders Improve management efficacy through research findings Understand and reduce management as a stressor Include tribal values and TEK in policy and management Sustain genetic diversity to ensure resilience & resistance

Group C: Invasive Species Interactions With Other Stressors Q4: Issues Likely to Become Important by billion more people – increased population stress Understand how to deal with uncertainty Understand impacts of trade and globalization Need increased international collaboration Changes in science expertise and capacity (e.g. long-term research) What impacts will new technologies have? Impacts of changes in ecosystem services

Group C: Invasive Species Interactions With Other Stressors Q5: How This Topic can Potentially Connect With Other Topics in Chapter Outline Interactions with other stressors cross-cuts all other topics Other stressors are an uncertainty multiplier To what extent will people focus on climate change or fire and not invasives? Could also be an opportunity.

Group C: Invasive Species Interactions With Other Stressors Q6: What are the Gaps in Knowledge and Current Research Models and databases Develop dynamic, spatial models Integrate multiple models and databases Spread models Improve forecasting ability Uncertainty Improve decision-maker ability to handle uncertainty

Group C: Invasive Species Interactions With Other Stressors Q6: What are the Gaps in Knowledge and Current Research Ecological data Knowledge of distribution and impacts of native & invasive species Large scale, long-term studies to track changes for mgt use Understand how other stressors change invasibility Integrate human dimensions with invasive species issues social values, costs & benefits, demographics, land-use changes
